AI Overrunning LinkedIn Content: Feast on the Posts Instead of Users

In the past two years, LinkedIn, the professional networking platform, has seen a significant shift in the way content is created and shared. The mass adoption of ChatGPT in 2023 marked the beginning of a spike in AI-written posts, transforming the platform's feed into an algorithmic echo chamber.

This change has not gone unnoticed. A study by Originality AI, published in 2025, found that 54% of long-form LinkedIn posts were likely written by AI. The study, conducted on 8,795 English-language posts between 2018 and late 2024, revealed that the use of AI-generated content on LinkedIn is now commonplace, with the baseline having shifted, making AI authorship seem normal.

However, this shift raises concerns about the homogenization of professional voices and perspectives. The continued use of AI-generated content could lead to a loss of the spark that makes content memorable and persuasive. Emotional nuance, hard-won insights, and small quirks of phrasing are smoothed away by the algorithm's influence, potentially eroding long-term trust.

LinkedIn offers built-in AI writing tools for premium users, making the act of posting a point-and-click exercise in producing "engagement-ready" copy. Generative AI is trained to excel at the safe, polite, and buzzword-heavy corporate speak characteristic of LinkedIn. As a result, posts start feeling interchangeable, making differentiation among professionals difficult.

Professionals who rely too heavily on AI risk being perceived as generic, the exact opposite of what LinkedIn was built to showcase. The lack of human texture in AI-generated content could negatively impact a professional's reputation and credibility on LinkedIn. Originality is now considered a rare skill on the platform.

The study by Originality AI, however, did not address the impact of AI-generated content on a professional's reputation and credibility on LinkedIn. The results of this investigation into the frequency of AI-generated long-form posts on LinkedIn were not found in the provided search results.

Despite these concerns, the use of AI-generated content on LinkedIn might win short-term visibility. However, it is crucial for professionals to strike a balance between leveraging AI tools and maintaining their unique voice and perspective. The platform, once promising to connect professionals and share insights, now sounds polished but feels hollow. It is essential to remember that LinkedIn was built to showcase the unique voices and perspectives of professionals, not to create an echo chamber of AI-written posts.
